M&I – AC 900F Controller 17
Section 2 Configuration
This section provides information on the AC 900F controller configuration for
single and redundant operation.
The AC 900F controller features a modular design. The basic components are a PM
CPU module, CI/CM PROFIBUS communication interfaces and S700 I/O modules.
The external 24 VDC voltage required to operate the controller can be provided by a
CP-C power supply unit, for example.
Configuration levels
The AC 900 F controller in basic configuration comprises the PM CPU module and
two TA dummy couplers designed to protect the unused C1/C2 slots. The on-board
Ethernet interfaces and serial interfaces of the CPU module are available for field
communication.
